Infineon REF‑22K‑GPD-INV-EASY3B

Reference Design for a General Purpose Drive

Infineons reference design REF-22K-GPD-INV-EASY3B is an industrial motor drive for three-phase 400 V AC grids and has a nominal power of 22 kW. It is a general purpose drive developed for applications like pumps, fans, compressors, conveyor belts. The design includes EMI filter, pre-charge and capacitor bank, isolated power supplies, power module, controls and heat sink with fan. It can be operated directly on a three-phase grid, enabling a fast evaluation of Infineon technologies such as IGBT7, gate driver, current sensor and control in one system.

Infineon uses a broad variety of TDK products in this reference design, and shows how the TDK product spectrum can cover many of the passive components that typically accompany the semiconductor components in such general purpose power electronic designs.

Note: Boards do not necessarily meet safety, EMI, quality standards (for example UL, CE) requirements.
